Jan Marinus Hoppema

Jan Marinus Hoppema is a senior research scientist at the Alfred Wegener Institute (AWI), specializing in physical oceanography with a focus on the carbon cycle, biogeochemistry, and polar regions. He holds an honorary professorship at Hochschule Bremerhaven. His work emphasizes the Southern Ocean and Arctic, particularly their roles in global carbon sequestration and climate dynamics.

Research interests include ocean-atmosphere CO2 exchange, Weddell Gyre circulation, and the impacts of sea ice on stratification. He co-edits the journal Ocean Science and contributes to major initiatives like the MOSAiC expedition and GLODAP data products. His recent projects address ocean acidification, long-term nutrient trends, and the influence of physical processes on biogeochemical cycles.

Key contributions include analyzing air-sea gas exchange in the Arctic, reconstructing historical CO2 levels, and advancing methodologies for oceanographic data standardization. Hoppema collaborates globally on climate change research, emphasizing interdisciplinary approaches to understand polar ocean dynamics.
